The length of each module is determined by a distance divisible by the length of the skirt liner on the standard skirt panel. This ensures standard positioning of the drop down idlers for easy access to conveyor idler rolls whilst also allowing for standardisation in length for all of the guards and covers on the conveyor.

The dust cover supports double up as skirt and guard supports which creates more space in the conveyor skirting area, allowing maximum access to all skirt rubber and skirt wear plates. Ensuring that all of the components are identical helps speed up the design, manufacture, installation and most importantly the maintenance of the conveyor system.
